• Ovine footrot is a contagious disease with important economic and welfare impacts. Typical signs are lameness, interdigital inflammation underrunning of the horn. Transmission Dichelobacter nodosus favoured by warm, wet environments. aprV2/aprB2 genes targets for PCR diagnosis virulent vs. benign strains. Control measures culling, footbathing, vaccination antimicrobial treatment. Footrot foot...

The aim of this study was to determine the proportion of Dichelobacter nodosus, Fusobacterium necrophorum and Treponema spp. in sheep with different clinical manifestations of footrot compared to healthy sheep both at flock and individual level. The second aim was to characterise D. nodosus with respect to virulence, presence of intA gene and the serogroups. Swab samples (n=1000) from footrot-a...

Footrot, including interdigital dermatitis, is caused by Dichelobacter nodosus cause the majority of lameness in sheep in the UK. Lame sheep often have overgrown hoof horn but recent evidence has indicated that trimming overgrown hoof horn increases recovery time, and that routine foot trimming of the flock does not reduce the prevalence or incidence of lameness. The objectives of this study we...

Introduction Dichelobacter nodosus is the causative agent of severe footrot, a contagious debilitating disease which affects ruminants particularly sheep and goats. The disease is characterised by separation of the hom of the hoof from the underlying soft tissues resulting in lameness, loss of body condition and reduced wool production (Rood et al. 1996). The first case of footrot in Malaysia w...

A study was conducted in a feedlot in Alberta, Canada, to compare the clinical efficacy of a single injection of ceftiofur crystalline free acid sterile injectable suspension with three daily treatments of ceftiofur sodium sterile powder for the treatment of footrot. Use of a long-acting antimicrobial to treat footrot would reduce labor costs and hospital pen space requirements during high-risk...

In this study it was aimed to isolation and identification by PCR of specific agent from ovine footrot in Kars district and thus determination of prevalence of disease. To this end, 8,970 sheep belong to 10 different flocks were examined clinically, and in 1532 of these (17.07%) were found lameness for various reasons. Out of 247 (2.75%) of these cases were evaluated to be footrot suspect clini...

Footrot is a highly contagious disease of the feet of animals, characterized by the separation of keratinous hoof from the underlying tissue. Co-infection of Dichelobacter nodosus and Fusobacterium necrophorum is the main reason of footrot in clinical. Environmental factors, such as warm and wet weather and pasture quality, etc. all are conducive for indirect transmission of bacteria among indi...

BACKGROUND The aim of this study was to investigate possible cross-infection of Dichelobacter nodosus in Norwegian farms practising co-grazing of sheep and cattle. METHODS Thirteen farms practising co-grazing of sheep and cattle were included in this descriptive study: five farms with a history of severe ovine footrot (Group I) and eight farms with free-stall housing of cattle and signs of mi...

Dichelobacter nodosus is a virulent, invasive, anaerobic bacterium that is believed to be the causative agent of ovine footrot, an infectious bacterial disease of sheep that causes lameness. Another anaerobe, Fusobacterium necrophorum, has been intimately linked with the disease occurrence and severity. Here we examine data from a longitudinal study of footrot on one UK farm, including quantita...

The aim of this study was to evaluate the clinical success of whole-flock systemic tilmicosin and enhanced biosecurity in eliminating active contagious ovine digital dermatitis (CODD) from sheep flocks. Thirty flocks in the UK were randomly allocated to receive either treatment as usual (as per the farmer's normal routine) or whole-flock treatment with tilmicosin, together with isolation and ex...
